Abstract
In a case where an image forming apparatus operates as a master station that determines a communication channel to be used in wireless communication, the image forming apparatus transmits a second trigger frame, which is compliant with the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard and includes information indicating that carrier sense is to be executed, to a slave station apparatus connected to the master station.
Claims16
A communication apparatus comprising:
- at least one memory and at least one processor and/or at least one circuit which function as:
- a communication control unit configured to enable at least one of a first mode for performing wireless communication via an external access point, wherein the external access point is located outside the communication apparatus, and a second mode in which wireless communication is not performed via the external access point outside the communication apparatus;
- and
- a transmission unit configured to, in a case where the communication apparatus operates as a master station that is configured to determine a communication channel to be used in the wireless communication in the second mode while at least the second mode is enabled, transmit a trigger frame compliant with the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard to a slave station apparatus connected to the master station, the trigger frame including information indicating that carrier sense is to be executed.

A printing apparatus comprising:
- at least one memory and at least one processor and/or at least one circuit which function as:
- a communication control unit configured to enable a mode in which wireless communication is not performed via an external access points outside the printing apparatus;
- and
- a transmission unit configured to, in a case where the printing apparatus operates as a master station that is configured to determine a communication channel to be used in the wireless communication while the mode is enabled, transmit a trigger frame compliant with the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard to a slave station apparatus connected to the master station, the trigger frame including information indicating that carrier sense is to be executed.
1 more element
A method for a communication apparatus, the method comprising:
- enabling at least one of a first mode for performing wireless communication via an external access point, wherein the external access point is located outside the communication apparatus, and a second mode in which wireless communication is not performed via the external access point outside the communication apparatus;
- and
- in a case where the communication apparatus operates as a master station that is configured to determine a communication channel to be used in the wireless communication in the second mode while at least the second mode is enabled, transmitting a trigger frame compliant with the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard to a slave station apparatus connected to the master station, the trigger frame including information indicating that carrier sense is to be executed.
A non-transitory computer readable storage medium storing instructions for causing a computing device to perform a process comprising:
- enabling at least one of a first mode for performing wireless communication via an external access point, wherein the external access point is located outside the communication apparatus, and a second mode in which wireless communication is not performed via the external access point outside the communication apparatus;
- and
- in a case where the communication apparatus operates as a master station that is configured to determine a communication channel to be used in the wireless communication in the second mode while at least the second mode is enabled, transmitting a trigger frame compliant with the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard to a slave station apparatus connected to the master station, the trigger frame including information indicating that carrier sense is to be executed.
A method for a printing apparatus, the method comprising:
- enabling a mode in which wireless communication is not performed via an external access points outside the printing apparatus;
